Which fluid should I use with Hyfuser?

ND FLUID 01 and 02 are recommended. Do not use other cosmetics, toner, ampoules, or serums.

Can I use purified water?

Purified water may be used. However, nozzle, spray, or device faults confirmed to have resulted from purified-water use are not covered under warranty; coverage is determined after product inspection.

How many uses are in one FLUID vial?

One 10 mL vial provides approximately 15 uses. The actual number varies with the amount and method of each use, and this is not a daily-use recommendation.

Is incidental eye contact okay?

A small amount of incidental eye contact can occur within normal facial use. Do not deliberately spray toward the eyes. If stinging or discomfort occurs, stop use and rinse with clean water.

Can I use it during pregnancy or nursing?

The product-use policy has no restriction based on pregnancy or nursing. Check the full ingredient list first if you have ingredient sensitivities or a history of allergies.

How far from the face should I hold it?

Hold it about 15-20cm away and keep the device moving for a thin, even application.

What should I do if the spray is weak or does not come out?

Stop use and lightly tap the device body with your fingertips. This helps the FLUID reach the spray unit inside; do not hit the device hard or turn it over and shake it. Try it again, then wipe away dried fluid around the nozzle and contact area and check the FLUID level, charge, and vial fit if there is no improvement. If the problem continues, submit a service request through DOSIÉ CARE.

Ingredients

N/A (Device)

What goes inside shapes the routine.

Hyfuser is a skincare device for applying fluid in a thin, even layer. Ingredient names matter, but so do formula texture, spray consistency, and nozzle condition. DOSIÉ guides use around dedicated FLUID 01 and 02.

DOSIÉ FLUID 01 and 02 are recommended for Hyfuser.
Purified water may be used, but a fault confirmed after product inspection to have been caused by purified-water use is not covered under warranty.
Choose FLUID 01 for dull or dry-looking days, and FLUID 02 for texture-and-tone concerns.
If the spray is weak or stops, lightly tap the body and try it again; if there is no improvement, check the nozzle, FLUID level, charge, and vial fit.

Check these basics first

On the first day, set the device and fluid conditions before experimenting with more ingredients.

Basic: Dedicated fluid. DOSIÉ FLUID 01 or 02 is recommended. Purified water may be used, but a fault confirmed after product inspection to have been caused by purified-water use is not covered under warranty.
Choice: 01 for radiance, 02 for texture. Choose 01 when skin looks dry or dull. Choose 02 when texture or tone looks uneven. Start with one fluid at a time.
Care: Tap lightly if the spray is weak or stops. Stop use and lightly tap the device body with your fingertips to help the FLUID reach the spray unit, then try it again. Do not hit the device hard or turn it over and shake it.

Dedicated FLUID is recommended; check the purified-water warranty limit.

Other cosmetics can change spray performance and nozzle condition. Purified water may be used, but faults confirmed after product inspection to have resulted from that use are excluded from warranty coverage.

DOSIÉ recommends FLUID 01 and 02.
Do not add other cosmetics, ampoules, serums, or toner.
Product inspection determines whether purified-water use caused the fault before warranty coverage is decided.
For the first use, avoid custom mixes and start briefly with an official fluid.

FLUID 01 and 02 have different roles.

01 and 02 are not scent or version differences. Choose 01 for a radiance routine on dry or dull-looking days. Choose 02 when texture or tone looks uneven.

FLUID 01 is a radiance routine based on NMN, 24K Gold, and nanodiamond.
FLUID 02 is a soothing and tone-care routine based on PDRN, panthenol, and nanodiamond.
On sensitive-feeling days, use one fluid lightly instead of layering both.

If the spray is weak or stops, tap the body lightly.

Stop use, lightly tap the device body with your fingertips to help the FLUID reach the spray unit, then try operating it again. Do not hit the device hard or turn it over and shake it.

After tapping lightly, try operating the device again.
If there is no improvement, wipe dried fluid from the nozzle and contact area.
Check the FLUID level, charge, and vial fit, then submit a service request through DOSIÉ CARE if the issue continues.
